A computation of frequency characteristics was made with the feeding device of typical weaving machines now used. It shows that:
(1) The automatic control device does not act efficiently if the unevenness of warp-tension exceeds 4_??_150 cycles per minute.
(2) When the tension unevenness is 5 to 7 cycles per minute, it is kept under control at 1/10.
(3) When the unevenness is 0.1 cycles per minute, it is kept under control at 1/104.
(4) When the frequency is less than 80 cycles per minute, the weight-load-type shows better control characteristics than the spring-load-type.
(5) The weight-load-type has such an unique characteristic that the unevenness from 1 to 200 cycles per minute is kept under control at 1/1.8, irrespective of frequency.
